INVENTOR J, H. WEBB ATTORNEYS- United States Patent ANTI-SLIPPING DEVICE FOR THE FEET Joseph H. Webb, McKinney, Tex. Application June 18, 1957, Serial No. 666,396

4 Claims. 01. 367.6)

This invention relates to the movement of one object relative to another and specifically to the movement of animate objects relative to inanimate or to locomotion, and to equipment employed for facilitating locomotion and for rendering relative contact and therefore more certain.

The invention relates more particularly to equipment for application to the feet by means of which more positive traction is accomplished and possibility of slippage is substantially eliminated so that it is possible to walk or run over terrain which is slippering because of ice or otherwise.

Devices for attachment to the shoes to prevent slippage of the latter have not been satisfactory for numerous reasons including because they were complicated and expensive, did not fit properly and for other reasons.

It is an object of the invention to provide antislipping devices for attachment to the shoes worn on the feet, which attachments are of simple and inexpensive construction, easy to manufacture from readily available materials, can be easily appplied, and which make it possible to walk without slipping on ice or other slippery or treacherous surface and which devices will readily fit or conform to the shoes of the wearer.

Other objectives and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing, wherein:

Fig. 1 is a side elevation illustrating one application of the invention;

Fig. 2, a perspective;

Fig. 3, a section on line 3-3 of Fig. 2; and

Figs. 4 and 5, top plan views of the left and right antislipping devices without the attaching straps.

Briefly stated, the invention comprises a pair of side .frames which are substantially parallel along their rear or heel portions but are spaced a greater distance apart at each side along the forward portions of the foot to more closely conform to the configuration of a shoe to which they are intended to be applied. The forward and rear portions of the side frames are angularly disposed with greater transverse angularity at the inside of each foot.

The side frames are connected by a series of crossbars or frames, one adjacent each the rear intermediate and forward portions of the side frames with such crossframes being relatively wide and flat and with a rear cross member disposed at the rear end of the side members and being L-shaped in cross-section so that the upstanding flange will cause the heel to be retained with in the flange. The side frames and cross members are connected by a series of rivets and with a nail extending downward at each end of each cross-frame.

With continued reference to the drawing, the antislipping or positive traction devices of the present invention are made, one for the left foot and one for the right foot of the wearer. The one for the left foot comprises a left longitudinal side frame having a relatively straight L-shaped portion 10, a forward portion 11 and a slightly l CfZ angular intermediate portion 12, while the frame for the right side of the left foot comprises a rear portion 13,

a forward portion 14 and an intermediate angular cou necting portion 15, disposed at a slightly greater angle than the intermediate portion 12, in order to more closely conform with the general shape of a shoe. manner the device for the right foot is composed of a left rear portion 16, a forward portion 17 and an angular intermediate or connecting portion 18, while at the outer or right side of the right foot is a rear portion 19, a'

an upstanding flange which limits the rear motion of the shoe when the deviceis applied. The cross bars are connected to the side frames by means of a series of rivets or other fasteners 26, and a series of spikes or cleats 27 are provided in the form of nails having their heads 28 beneath the center of each end of cross bars 22, 23 and 24 and extending through the respective side members so that they are firmly held in place. The side frames provide elongated openings or slots 29 and 30 in the left and right heel portions 10, 13, 16 and 19, and additional openings or slots 31 and 32 in the front side frames 11, 14, 17 and 20. Within these slots are disposed pairs of anchor straps 33 and 34, each including a buckle or other fastener 35 by which they may be fastened together, the straps being provided with openings 36 and 37 for the adjustment of such straps. The strap 33 likewise is provided with a heel adjusting strap 38 having one end secured by a rivet 39 to the strap 33 and with its other end provided with openings 40 for receiving the tongue of a buckle 41 caried by a strap 42 secured by a rivet 43 to the strap 33. The antislipping or positive traction device as illustrated in Figs. 1, 2, 3 and 5 are for attachment to the right foot. It would be understood, of course, that straps the reverse of those as shown in Fig. 2 will be employed with the side frames and cross bars of Fig. 4 to form a similar anti-slipping device for attachment to the left foot.

The device as illustrated and described may be easily and economically manufactured from readily available materials and will provide the positive traction needed for ice and other slippery surfaces.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claims.

What is claimed is:

1. An anti-slipping device for attachment to a shoe for the foot comprising a side frame for disposition along the inner side of the foot, a side frame for disposition along the outer side of the foot, a rear end frame connecting said side frames, said side frames having spaced slots for the reception of securing straps and L-shaped in cross-section whereby part of said frames may support and part may assist in retaining a shoe therewithin, a series of connecting cross bars, one near each the rear, the front and the intermediate portions of said side frames, said side frames being parallel along their forward and rear portions and with intermediate portionsv extending outwardly and joining said forward and rearportions in a manner that the forward portions of the side frames are spaced apart a greater distance than the rear portions thereof and the inner side of the foot will be located at one side of the longitudinal center of said frames, fasteners connecting said side frames and cross.

bars, cleats for penetrating a slippery surface, said cleats. having end portions confined between said side frames.
